BRUSH FOR POWER MARKING-MACHINES.

Application filed August 29, 1910. Serial No. 578,535.

T 0 all whom it may concern:

Be it known that 1, WILLIAM VJ. MCCOY, a citizen of the United States of America, and resident of Cincinnati, county of Hamilton, State of Ohio, have invented certain new and useful Improvements in Brushes for Power hGfarking-h fachines, of which the following is a specification.

The objectof my invention is a simple means both of cleaning the type of a power marking machine before the application of ink, and of distributing the ink on the type after it has been applied thereto, without interfering with the operation of marking the goods.

In the accompanying drawings forming a part hereof, Figure 1, is a perspective view of a power-marking machine, provided with a brush and a n'i-echanism for actuating the same embodying my invention. Figs. 2, 3, and i, are side elevations upon a somewhat enlarged scale of the type wheels, inking-pad, brushframe, the levers and arms, upon which said parts are mounted, and the cams for actuating them, and showing them at various stages of the operation. Fig. 5, is a perspective View of the brush and a part of the brush-frame.

Referring to the parts: Base A has at its sides journal lugs a, in which the main shaft B is journaled. At the forward edge of the base are journaled lugs a, 64 between which is mounted shaft d, upon which lever arm D, is journaled. The type wheels d are journaled upon shaft (Z which is carried at the outer end of arm D. Lever arm D, has at its lower end a roller d which engages a cam shaped groove 6, in a cam b, which is secured upon the shaft B, the rotation of which effects a reciprocation of the arm D, to carry the type wheels into contact with the table F, upon which the goods f to be marked are placed.

Inking-pad E is carried at the outer end of arm 6, which is pivoted at its inner end to arm a, which is pivoted at its lower end to the base A and carries roller e which contacts with cam E, which is secured upon the shaft B, to effect the movement of the pad E toward and from the type wheels. Arm 6 is connected by links 6 with the arm D, said links being pivoted at one end to the arm D, and at the other end to the arm 6.

Brush-frame G, has side members which are hung at their upper ends upon the shaft (Z 0f the type-wheels, and at their lower Specification of Letters Patent.

Patented Nov. 15, 1910.

ends are connected by links g, g arm a, the connections of said links being pivotal.

The cam groove Z) is crescent shape, the part 6 thereof being eccentric to the shaft B, and the remainder being concentric with the shaft B, so that while the roller (Z is in the eccentric portion, thelever arm D, is moved toward and returned from the table F, and that while the roller (Z is in the concentric portion, the arm D remains in a normal position with the type-wheels raised from the table. The cam E has a portion a which is eccentric to shaft B and which when brought in contact with the roller 6 moves the pad E and the brush-frame forward, and a concentric portion 6 which when in contact with the rollers 6, holds the pad out of contact with the type-wheels. The cams Z), and E, are so positioned upon the shaft B, that the eccentric portions thereof come into contact with their respective rollers consecutively.

The links 9, g are made of a length such that when the inking-pad is in its normal or retracted position, the brush G stands in the rear of the contact points of the type, so that the brush does not interfere with the type coming in contact with the table F, and so that when the pad is in its forward position, the brush stands in front of the contact point of the type-wheels. Thus in the forward movement of the brush-frame, the brush sweeps over the type in front of the pad, and in the return movement the brush sweeps over the type back of the pad.

in operation supposing the shaft B. to have a motion in the direction of the hands of a clock, and to be in the normal position shown in Fig. 3. The roller d entering in the eccentric portion 6 will start the typewheels toward the table, and when the roller clfl reaches the center of said eccentric portion of the way 6 the type-wheels will have come in contact with the table F, and when the roller (Z has reached the opposite end of said eccentric portion, the typewheels will have been raised to their normal position again, in which they will remain until the parts again resume the position shown in Fig. 3. lVhile the roller (Z is in said eccentric portion of the way 6, the concentric portion 6 of the cam E, has been contacting with the roller 6 hence the pad and the brush-frame have maintained their normal position in relation to the typewheels. After the roller d has emerged from said eccentric portion 5 the eccentric portion 6*, contacts with roller 6 This advances the forward end of arm a, carries the brush-frame forward and causes the brush g to contact with the type-wheels and to clean them. When the center of the eccentric portion 0, contacts with the roller 0 the inking-pad E, contacts with the type, which are to be brought into contact with he goods upon the table. Further rotation of the cam E, retracts the arm a, withdraws the pad E, from the type-wheels, and draws the brush backward over the type thus distributing the ink thereover. WVhen the roller 0 reaches the concentric portion 0, the type have been properly inked, and the ink has been distributed properly, and the parts are in position to carry the typewheels into contact with the goods to secure a clean cut impression of the type thereon.

Vhat I claim is:

1. In a power-marking machine, the combination of a type-bearing arm, type-wheels mounted upon said type-bearing arm, a brush-frame mounted upon the type-wheels, a brush carried by the frame and contacting with the Wheels, a pad, a second arm adapted to carry the pad into contact with the Wheels and a link connecting the frame and the second arm, whereby the brush distributes the ink over the type.

2. In a power-marking machine, the combination of type-wheels, a shaft upon which the type-wheels are journaled, a lever arm upon which the shaft is mounted, a brushframe pivoted upon said shaft, a brush mounted upon said frame, an inking-pad, an arm at the outer ends of which said inking-pad is mounted, links connecting the brush-frame and the arm of the inking-pad and mechanism for actuating said lever arm and the arm of the inking-pad, whereby the brush is carried over the type-wheels in advance of the pad and is carried back over the type-wheels in the rear of said pad.

3. In a power-marking machine, the combination of a lever arm, type-wheels mounted at the forward end of said lever arm, an arm, an inking-pad mounted at the forward end of said arm, links connecting the padbearing arm with the bruslrframe, and the lever arm, a cam having an eccentric portion to contact with the lever arm, and effect a reciprocation of the type-wheels toward and from the goods to be marked, and a second cam having an eccentric portion to effect the reciprocation of the pad-bearing arm, said eccentric portions being in a position so that they are brought into contact with said parts consecutively, whereby the inking of the type and the distribution of the ink thereon, is effected while the type are out of contact with the goods.
